SILO OR TANK.

SPECIFICATION forming part of Letters Patent No. 766,708, dated August2, 1904.

Application filed May 26, 1904. Serial No. 209,962- (No model.)

T 0 all whom it may concern:

Be it known that I, LYMAN G.LEASE, of WVarren, in the county of Trumbulland State of Ohio, have invented certain new and useful Improvements inSilos or Tanks; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The object of this invention is to so construct the wall of a silo,tank, or other similar structure as to prevent outward crowding andinsure the firm retention of the blocks or tiles in place by means bothsimple and inexpensive.

The invention will be hereinafter fully set forth, and particularlypointed out in the claims.

In the accompanying drawings, Figure 1 shows a portion of a siloconstructed in accordance with my invention. Fig. 2 is a verticalsectional view showing the means for retaining the tiles in position.Figs. 3, at, and 5 are similar views of slight modifications. Fig. 6shows two blocks in side elevation.

The circular wall of the tank br inclosure is made up of layers ofblocks or tiles 1 after the manner common in wall constructions. Thetiles of all or some of the layers are formed on their upper and lowerfaces with central longitudinal grooves or recesses 2. Within thesegrooves are designed to be placed bands 3 and cement 4, the latter notonly serving to retain the several layers together, but also insures theproper retention of the bands, which serve to prevent the wall frombulging outwardly, as is liable to occur under the weight of the grainor other articles stored within the inclosure. In addition thereto thewall is further strengthened by an outer band or rod 5 encircling thestructure,such band fitting within grooves 6, formed in the outer facesof the blocks. This groove is of suflicient depth to permit the band 5to be entirely covered by an outer coating 7 of cement or plaster. (SeeFig. 3.)

In Figs. 1 and 2 I have shown the outer bands on every third layer, thebands 3 being between the blocks of the intermediate layers; but thismay be differently arranged.

In Fig. 3 I have shown the bands 5 encircling the same tiles that arealso secured by the bands 3, while in Fig. 4 the blocks of the severallayers encircled by the outer band 5 are shown without the upper andlower recesses 2, such being provided only in the blocks of theintervening layers, whereas in Figs. 1 and 2 all of the blocks of eachlayer are shown equipped with the upper and lower recesses, includingthe layers surrounded by the outer encircling" bands.

If desired, only every third layer may be equipped with the bands 3, theintervening layers being surrounded by the outer bands. (See Fig. 5.)

Each block or tile is made with a reduced end 8 (see Fig. 6) for fittingin the larger end of the next adjacent block, thereby adding additionalstrength to the structure and forming a tight joint which is preferablysecured by mortar.

From what has been said it will be seen that a silo or tank constructedin accordance with my invention will be strong and durable, the blocksor tiles being firmly secured as against outward bulging. Although Ihave shown the bands 3 as being rectangular in cross-section and thebands 5 as circular in cross-section, it is obvious that they may bemade of any desired shape, it only being essential that they formsufiicient anchorage in their connections with the tiles to insure theretention of the latter in place.

I claim as my invention 1. A silo or tank composed of layers of blocksor tiles having upper and lower longi tudinal grooves, rods or bandsfitted in said grooves, and outer encircling bands.

2. A silo or tank composed of layers of blocks or tiles the blocks ortiles of some of said layers having grooves in their outer faces, rodsor bands fitted in said grooves, and a covering for said grooves androds.

3. A silo or tank composed of layers of blocks or tiles, the blocks ortiles of some of the layers having upper and lower grooves, bands fittedin said grooves, blocks or tiles of others of said layers having groovesin their outer faces, and rods or hands fitted in said latter grooves.

4. A silo or tank composed of layers of In testimony whereof I havesigned this blocks or tiles, each block being reduced at specificationin the presence of two subscribone end to fit the larger end of the nextadjaing Witnesses.
